Page 8: Configuring The Ws500
External or Ring Config Type The WS500 has 13 modes of operation, numbered as “Types” 0 to 12. Each Type offers different features, different numbers of weld programmes and may use the input and output connections in different ways. The following table gives a brief description of what each Type does, and shows the number of weld programmes available for that option. - Page 9 WS500 Manual Configuring the WS500 Spot/repeat with retract Spot welding with single or repeated weld sequences with an input and output for controlling the “open” and “working” positions of the welding gun. Spot/repeat with counter Spot welding with single or repeated weld sequences with a counter that gives an output when the programmed number of welds has been reached.

In this mode, when a weld sequence has progressed beyond the Squeeze time, the sequence continues to completion, regardless of the Start signal.

Then press again to move onto the next parameter. At any point can be pressed to exit programming weld parameters. If the WS500 is in a mode that uses a counter, the COUNTER display will read . This is programmed in the same way. -

WS500 Manual Programming the WS500 Seam Welding Current Profiles In seam welding mode (Configuration mode 12) there are two weld pulses and two cool times available. These can be used to give a number of weld current profiles, as shown below. - Page 15 WS500 Manual Programming the WS500 Example settings: Weld 1 = Current Cool 1 = Weld 2 = Cool 2 = Heat 1 = Heat 2 = Example settings: Time Weld 1 = Current Cool 1 = Weld 2 = Cool 2 =...

“Configuration”). Having been configured, the timer must be programmed with the weld parameters for the job in hand. Several sets of weld parameters can be held in the WS500. Each set of parameters is called a “Programme”. (See section “Programming the WS500”.) -

Page 18: End Of Sequence Output
WS500 Manual Welding with the WS500 End of Sequence Output (Applicable to all modes except 7, 11 and 12) In Single Spot operation, at the end of the weld sequence the End of Sequence output switches on. If the Start signal is still present, the End of Sequence signal remains on until the Start signal is removed. - Page 19 WS500 Manual Welding with the WS500 In Repeat Spot operation the End of Sequence output switches on for the Off time between sequences, and for the time entered in the timer configuration as EOS Duration, after the final sequence. Start Signal Weld Sequence End of Seq.

When the number of welds completed equals the number of welds programmed as “End Count” the Count Output switches on. If “Stop at End” has been programmed, the WS500 will ignore Start inputs when this stage has been reached. If “Continue at End” has been programmed, welding will continue. -
Page 21: Cross Interlock
A cross interlock is an arrangement of welding controls that ensures no more than one control is welding at any time. This is to ensure that the mains supply is not over-loaded. WS500 offers a choice of two cross-interlocking schemes, called EXTernal and RING. EXTernal cross-interlock. -
